[0016] The following will be combined with the drawings Figure 1 - Figure 4 Further detailed description of the application.
[0017] Embodiment:
[0018] An ink-jet printer nozzle anti-collision structure is used for protecting the nozzle of the ink-jet printer, referring to Figure 1 - Figure 2 , comprising a nozzle body 1, the nozzle body 1 is the prior art, which is used for spraying printing, the top of the nozzle body 1 is fixedly connected with a fixed seat 2, the top of the fixed seat 2 is provided with a connecting head 3, the connecting head 3 is convenient for being connected with the ink-jet printer, one side of the nozzle body 1 is provided with a mounting seat 4, the fixed seat 2 is fixed on the mounting seat 4 through a bolt 5, the bottom end of the mounting seat 4 is fixedly provided with a rotating shaft 6, rollers 7 are rotatably connected on the two rotating shafts 6, the two rollers 7 are symmetrically arranged on the two sides of the nozzle body 1, the two rollers 7 are convenient for moving the nozzle body 1, the mounting seat 4 is provided with an anti-collision assembly, the anti-collision assembly is convenient for protecting the nozzle body 1, avoiding the collision during the movement of the spraying operation;
[0019] In use, the nozzle body 1 is installed on the mounting seat 4, and then the mounting seat 4 is installed on the inkjet printer. In subsequent use, the nozzle body 1 is driven to move by the inkjet printer. At this time, the two side rollers 7 facilitate the movement of the nozzle body 1, and at the same time, the anti-collision assembly protects the nozzle body 1 during movement to avoid collision.
[0020] Referring to Figure 3 Figure 4 The anti-collision assembly includes a guide rail 8 fixedly connected to the mounting seat 4. The guide rail 8 is arranged at the middle position of the mounting seat 4. A sliding block 9 is movably connected to the guide rail 8, so that the sliding block 9 can move on the guide rail 8. A plurality of mounting holes 10 are formed in the sliding block 9, which facilitates the installation of the device on the inkjet printer. A sliding groove 11 is symmetrically formed on both sides of the guide rail 8. The sliding block 9 is movably connected to the inside of the sliding groove 11. A guide rod 12 is fixedly connected to the inside of the sliding groove 11. The sliding block 9 movably surrounds the guide rod 12. A resilient member 13 is symmetrically arranged on both sides of the guide rod 12. One end of the resilient member 13 is fixed to the guide rod 12, and the other end of the resilient member 13 is fixed to the sliding block 9.
[0021] In use, the device is installed on the inkjet printer through the plurality of mounting holes 10 on the sliding block 9.

When the nozzle body 1 is separated from the object, the resilient member 13 is reset to return to its original position, and the nozzle body 1 is reset. Thus, the nozzle body 1 is protected from collision during movement of the spraying operation.
